Narrative:
During takeoff in atl on runway 8R, at 6000 pounds less than maximum structural gross weight, the tailskid struck the runway at approximately 10.4 degrees of pitch. The winds were reported at 180 degrees at 7 KTS, with the wind direction varying from 150 degrees to 230 degrees. During the start of the rotation, the elevator felt a little heavy, but not too heavy to make a normal rate of rotation. Due to the heavy weight of the aircraft and the variable winds, I made a slower than normal rotation. However, the aircraft attained a pitch of greater than 10 degrees prior to liftoff, at which time the tailskid drug on the runway. I believe that the tailstrike could have been prevented if I had placed more emphasis on rotating at a slower rate -- taking into consideration the very heavy takeoff weight and the variable winds. Supplemental information from acn 397782: so heard a scraping noise during rotation and mentioned to crew after safely airborne. Corresponding amber 'tailskid' light on so's panel. Performed 'tail strike during takeoff' abnormal procedure from manual. Dumped 20000 pounds of fuel with ATC coordination and returned to atl for uneventful landing. Tailskid 'hook point' was scraped off and tailskid telescoping strut appeared to have been compressed 1 1/2 inches. Tailskid inspection clip was undamaged. Aircraft appeared to not have been seriously damaged.
Original NASA ASRS Text
Title: AN ACR B727 FLC MAKING A NEAR MAX GROSS WT TKOF WITH A QUARTERING TAILWIND HAD A TAILSTRIKE WHEN THEIR ROTATION ANGLE WAS TOO GREAT. THEY PERFORMED THE APPROPRIATE CHKLISTS, DUMPED FUEL AND RETURNED TO THE ARPT.
Narrative: DURING TKOF IN ATL ON RWY 8R, AT 6000 LBS LESS THAN MAX STRUCTURAL GROSS WT, THE TAILSKID STRUCK THE RWY AT APPROX 10.4 DEGS OF PITCH. THE WINDS WERE RPTED AT 180 DEGS AT 7 KTS, WITH THE WIND DIRECTION VARYING FROM 150 DEGS TO 230 DEGS. DURING THE START OF THE ROTATION, THE ELEVATOR FELT A LITTLE HVY, BUT NOT TOO HVY TO MAKE A NORMAL RATE OF ROTATION. DUE TO THE HVY WT OF THE ACFT AND THE VARIABLE WINDS, I MADE A SLOWER THAN NORMAL ROTATION. HOWEVER, THE ACFT ATTAINED A PITCH OF GREATER THAN 10 DEGS PRIOR TO LIFTOFF, AT WHICH TIME THE TAILSKID DRUG ON THE RWY. I BELIEVE THAT THE TAILSTRIKE COULD HAVE BEEN PREVENTED IF I HAD PLACED MORE EMPHASIS ON ROTATING AT A SLOWER RATE -- TAKING INTO CONSIDERATION THE VERY HVY TKOF WT AND THE VARIABLE WINDS. SUPPLEMENTAL INFO FROM ACN 397782: SO HEARD A SCRAPING NOISE DURING ROTATION AND MENTIONED TO CREW AFTER SAFELY AIRBORNE. CORRESPONDING AMBER 'TAILSKID' LIGHT ON SO'S PANEL. PERFORMED 'TAIL STRIKE DURING TKOF' ABNORMAL PROC FROM MANUAL. DUMPED 20000 LBS OF FUEL WITH ATC COORD AND RETURNED TO ATL FOR UNEVENTFUL LNDG. TAILSKID 'HOOK POINT' WAS SCRAPED OFF AND TAILSKID TELESCOPING STRUT APPEARED TO HAVE BEEN COMPRESSED 1 1/2 INCHES. TAILSKID INSPECTION CLIP WAS UNDAMAGED. ACFT APPEARED TO NOT HAVE BEEN SERIOUSLY DAMAGED.
